3. This configuration supports logging of debug output to a circular
buffer in RAM. This feature is discussed fully in this Wiki page:
http://nuttx.org/doku.php?id=wiki:howtos:syslog . Relevant configuration settings are summarized below:
File System:
CONFIG_SYSLOG_ENABLE=n : (Output debug info unconditionally)
CONFIG_SYSLOG=y : Enables the System Logging feature.
Device Drivers:
CONFIG_RAMLOG=y : Enable the RAM-based logging feature.
CONFIG_RAMLOG_CONSOLE=n : (We don't use the RAMLOG console)
CONFIG_RAMLOG_SYSLOG=y : This enables the RAM-based logger as the
system logger.
CONFIG_RAMLOG_NONBLOCKING=y : Needs to be non-blocking for dmesg
CONFIG_RAMLOG_BUFSIZE=16384 : Buffer size is 16KiB
NOTE: This RAMLOG feature is really only of value if debug output
is enabled. But, by default, no debug output is disabled in this
configuration. Therefore, there is no logic that will add anything
to the RAM buffer. This feature is configured and in place only
to support any future debugging needs that you may have.
If you don't plan on using the debug features, then by all means
disable this feature and save 16KiB of RAM!
